Benefits of technology

This patent describes a device for dispensing filler material onto a surface. The device includes a piston pump with a spill port that can adjust to changing volume. The device can be inclined to allow the filler material to flow towards the surface and wipe any depressions caused by the device's action. The device also includes a flexible wiper and a one-way valve to prevent the filler material from hardening in the outlet. A guard may be provided to prevent splattering of the filler material. Overall, the device provides an efficient and precise means for dispensing filler material.

Problems solved by technology

When using machines of the above type, the depression left in the material when the nail is driven to the required depth can be unacceptably unsightly.
This is a labor-intensive operation which increases the cost of the process.

Embodiment Construction

[0033]FIGS. 1 to 3 show important features of a conventional nailgun, in which nails 43 are formed into a strip to be fed through a slot 45 in a gun barrel 35 from a magazine (not shown) held by mounting holes 48. A drive pin 42 is powered by piston 41 by gas pressure applied to the upper surface of the piston 41, the flow of gas being regulated by a first trigger mechanism (not shown). A second, interlocking trigger mechanism is attached to a movable foot 44 so that, in order for the nailgun to operate, both trigger mechanisms must be activated. This is a well-known safety feature and prevents accidental firing of the nailgun.

[0034]The foot 44 is spring loaded to an extended position, as shown in FIG. 2. In order to activate the trigger mechanism, the foot 44 must be depressed as shown in FIG. 3 so that the end of the nailgun barrel 35 is brought close to a wooden block 36.

[0035]In accordance with the present invention, when the two trigger mechanisms are activated, the drive pin 4...

Abstract

A gun device for driving a fixing element into a work surface includes a driving mechanism for the fixing element. The gun device further includes supply means for a filler material, the supply means having an outlet arranged to deposit filler material on the work surface at a point corresponding substantially to an entry point of the fixing element into the work surface. Actuating means is provided for actuating the supply means in response to advancement of the gun device towards the work surface to deposit filler material on the work surface. Movable means is provided, movable in response to retreat of the gun device from the work surface, to pass across the work surface over the end of the fixing element so as to cause deposited filler material to smooth and fill any depression formed in the work surface as a result of operation of the gun device.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to a device for driving a fixing element into a work surface, for example a constructional material. The device may be used for driving fixing elements such as nails into wood, and more particularly but not exclusively the invention relates to a nail gun for use such as in the construction of pallets and crates, fixing of floor boarding, manufacture of furniture and the fixing of trim and architraves.[0002]When using machines of the above type, the depression left in the material when the nail is driven to the required depth can be unacceptably unsightly. To improve the finish, the depressions might be filled with a wood-filler which could require further dressing when cured. This is a labor-intensive operation which increases the cost of the process.[0003]It is an object of the present invention to provide a device for driving a fixing element into a work surface and simultaneously for filling any depression formed in the mate...
